Aluminum windows, sliding systems, folding walls and curtain walls for new residential development

In Amsterdam-West, the next phase of the Laan van Spartaan residential district is currently under heavy construction. Commissioned by BPD Ontwikkeling, UBA Bouw is constructing 21 ground-level single-family homes with four floors and six rooms and 298 apartments, 122 for sale and 176 for rent, to a design by the architectural firms KOW and Studioninedots.

Large areas of glass must provide the necessary light and comfort in the various residential units. The construction team chose various aluminum window and facade systems from Aliplast: Max Light and Futural windows, VG 500 sliding windows and Panorama folding walls, as well as MC Wall curtain walls. The aluminum systems are professionally installed by Aliplast partner Stalku Geveltechniek Zoetermeer.

Window systems Futural and Max Light

Futural is a three-chamber system with thermal break for interior aluminum windows and interior and exterior doors. This aluminum window system has an installation depth of 51 mm for the outer frame and 60 mm for the sash and a glass thickness of up to 35 and 40 mm, respectively. The windows have a U-value of 1.5 W/m²K, Class 4 airtightness and a sound attenuation Rw of up to 45.2 dB.

"The Max Light aluminum windows are designed for architectural projects that prioritize the combination of minimalist aesthetics, high-quality thermal insulation and comfort. There are 4 variants - Design, Invisible, Modern and Steel - the last two of which are being used in the Laan van Spartaan project," said Marc Mulders, sales manager for the Netherlands at Aliplast.

"These Max Light Modern and Steel have a minimum view width for an internal window of 35 mm both for frame and sash. For an interior door, frame and sash have a view width of 35 and 68 mm respectively, for an exterior door this is 15 and 88 mm respectively. At the contractor's request, we developed a special profile for Laan van Spartaan. While the stop is normally 15 mm, we opted for 22 mm. As a result, the frames can be placed better and there are more adjustment possibilities, which causes fewer problems on the building site."

Sliding systems VG 500 and folding walls Panorama

With the VG500, the construction team also chose a universal sliding window that more than meets all contemporary requirements around glass thickness, sash height and insulation values. It is the solution for larger sizes with a sash weight of up to 200 kg as a lift-slide and 250 kg as a sliding system and a glass thickness of up to 43 mm. This system has a U-value of 1.2 W/m²K. Thanks to the flat sill, this sliding window is barrier-free. The Panorama folding wall is the superlative of a sliding window, because it allows a house to slide open completely. In fine weather, it provides the ideal experience of the outdoor space, and in bad weather, a perfect closure. This elegant folding wall system can be supplied 2- to 8-piece with a maximum sash weight of 100 kg. It has a built-in depth of 75 mm with glazing between 16 and 50 mm.

MC-Wall curtain walls

Finally, the MC Wall curtain wall was also selected. "In developing this solution, we made every effort to maximize the architect's design freedom. For example, vertical and sloping facades can easily be linked together. Thanks to the glass weight of up to 600 kg, gigantic window sections are possible," Mulders concludes. "With a U-value of 0.97 W/m²K, this all-in-one curtain wall also scores well in terms of insulation, and with a glass thickness of 59 mm, almost all available glass types can be integrated. In addition to aesthetics and insulation, however, fire resistance also catches the eye. Indeed, certificates for both EI30 and EI60 are available for this system."
